Why did AirDrop change the file time attribute for one of my photos?

I was copying over one of my photos from the Photos app using the AirDrop share option. Once the file copied over to my Mac I was very surprised to notice that the created and modified file time attributes were listed for the time the file was air dropped, not the actual content creation time like seen in the same File Attribute snippet shown below. Did AirDrop modify the file, what's going on here exactly?
